1. Introduction
Intertrochanteric fracture is common among the elderly, especially those with osteoporosis [1-5]. While the mortality rate related to intertrochanteric fracture has reduced due to medical care advancements in recent years [6], this kind of fracture still accompanies a considerable mortality rate among the elderly. Early mortality (within one month) among these patients has been reported to range between 10%-30% in various studies [7-12].
Several factors contribute to the mortality of patients with intertrochanteric fractures, including advancing age, delays in operative treatment, underlying diseases, duration of surgery, and anesthesia methods [13]. Additionally, studies have mentioned the influence of surgeons’ experience, hospital patient load [14], and obesity [5] on mortality rates.
Due to the uncertainty of mortality causes and lack of comprehensive studies on this subject, this study was conducted to compare the short and long-term mortality rates and the hospitalization duration in intertrochanteric fracture patients receiving early and delayed surgical treatment.

2. Methods
The utilized data from patients with femoral intertrochanteric fractures who were referred to Ayatollah Kashani Hospital, Isfahan City, Iran from 2018 to 2020.
The inclusion criteria included patients with intertrochanteric fractures who underwent surgery between 2018 and 2020 and had adequate information available in their medical records or accessible through family members.
We collected demographic data, underlying diseases, duration from admission to surgery, surgery duration, and length of hospital stay after surgery from the related documents. Patients were categorized into two groups based on surgical delay, those with delay (surgery initiated more than 48 hours after hospital admission), and those without delay.
Patients’ mortality status, post-surgery complications, and the period after surgery to their death were obtained through phone calls. Patients’ death was classified into short-term (within one month after surgery), and long-term (within one year after surgery).
Data were analyzed using SPSS software, version 26 with the chi-square test and t-test.

3. Results
A total of 308 patients with intertrochanteric fractures with a mean age of 62.35±10.15 years were selected. Among them, 230 patients (74.7%) were men and 78 patients (25.3%) were women. Also, 8.4% of them had underlying diseases. The mean duration of surgery was 1.23±0.57 hours, and the mean length of hospital stay was 13.99±3.27 days. Delayed surgery was observed in 47 patients (15.3%), and 261(84.7%) underwent surgery without delay. Furthermore, 7 patients (2.3%) died within one month post-surgery, and 13 patients (4.2%) died within one year after surgery.
The subjects in the two groups had no significant difference in their age and gender, but the existence of underlying disease was significantly higher in the group with delayed surgery (P<0.001). Moreover, the mean length of hospital stay (P<0.001), duration of surgery (P<0.001), short-term mortality (P=0.01), and long-term mortality (P<0.001) were significantly higher in the delayed surgery group (Table 1).



4. Discussion
While delaying surgery for a femoral intertrochanteric fracture may allow for more comprehensive patient evaluation and medical optimization, it also introduces various complications, such as bed sore, thromboembolism, infection, delayed rehabilitation, prolonged hospital stay, and increased mortality rates.
In our study, we observed higher short and long-term mortality rates among patients with delayed surgery. There is controversy in recent studies concerning the correlation between delayed surgery and mortality rates. Leung et al. reviewed 42 studies and found that early surgery was associated with lower side effects, mortality rates, bed sores, and hospitalization duration. However, evidence of short and long-term mortality was diverse [15]. This is probably due to the small sample size, diverse definitions of delayed surgery, and failure to evaluate the cause of the surgery [16]. Daugaard et al. investigated 38,020 patients from 2003 to 2010 and reported that delayed surgery after acute pelvic fracture accompanies with a considerable increase in short-term mortality (odds ratio (OR)=1.3 in 24-hour delay) [16]. Similarly, Poór et al. found that increased comorbidity significantly increased mortality in patients with hip fractures, highlighting the critical nature of timely surgery [17]. Rosso et al. concluded that surgical treatment for pelvic fractures should be performed within 48 hours [18].
In our study, gender and age were not related to delayed surgery, but patients with underlying diseases were more likely to experience delayed surgeries, with longer surgical durations and hospitalizations observed in this group.
A study by Cha et al., similar to ours, found a correlation between delay in surgery and mortality rate in patients with intertrochanteric fracture [19]. While investigating factors contributing to surgical delays, they did not explore the impact of surgery duration on delays or the effect of delay in surgery on the length of postoperative hospitalization. By investigating the cause of the delayed surgery, they found that age (P=0.312) and gender (P=0.7102) were not determining factors for the kind of surgery (early or delayed). In addition, they found that factors like medications and comorbidities, such as pneumonia or heart disease (OR=2.780, 95% confidence interval [CI], 1.012%, 7.640%, P=0.047), have a significant relationship with the mortality rate related to pelvic fracture. Charlson’s comorbidity index has shown increased marginal mortality (OR=1.431, 95% CI,  0.958%, 2.137%, P=0.080) in these patients compared to delay in surgery due to hospitalization factors, such as hospitalization on weekends or holidays, or delay due to the surgery schedule or consultation with other specialties. Therefore, the trigger of the higher rate of mortality in patients with delayed surgery may be in part due to the inappropriateness of the patient’s health status, such as drugs or medical status.

5. Conclusion
Most patients with underlying disease who undergo delayed intertrochanteric fracture surgeries experience more length of hospitalization and surgery duration. This delay brings about more short and long-term mortality rates among patients. Timely surgical intervention is crucial to improve outcomes in these patients.
